GAS BURNER AND M HOD or MAKING SAME.

Application filed December 10, 1924. Serial No. 754,887.

This invent-ion, as indicated, relates to a gas burner and method of making'the same.- More particularly it comprises a casing provided with a slotted top plate, the slots preferabiy being arranged either transversely or radially. It also includes a top plate formed of two members preferably formed of companion castings, portions of the edges of which when assembled are spaced from each other so as to provide the desired slots.

- While the invention has been shown and described in connection with a gas burner construction it is to be understood that certain features of the construction are adaptable for use in the manufacture. of other articles;

than gas burners and that it is not intended after fully described and particularly pointed out in the claims. r

The annexed drawings and the following description set forth in detail certain means and one mode of carrying. out the inven- 'tion, such disclosed means and mode illustrating, however, but one of various ways in which the principle of the invention may be used. r

In said annexed drawings Fig.1 is a top plan view. ot'an elongated type of burnerernbodying the features-of the invention; Fig. 2 is a longitudinal sectional view of the construction shown in Fig. 1, taken along the line 2-2 looking in the direction of the arrows; Fig. 3 is a longitudinal sectional view of the top plate taken along the line 3-3 shown in said figure looking in the direction of the arrows; Fig. 4 is a transverse sectional view of the construction shown in Fig. 1 taken along the line H shown in said figure looking in the direction of the arrows Fig. 5 is a side elevation of reduced size showing a burner of the type shown in Figs 1 and 2 mounted upon atapered mixing arm;-Figs. 6 and 7 are top plan views of the respective complementary members which, when assembled, form the top plate of the longitudinal type of burner; Fig. 8 is a top planview of a circular type of burner embodying the prinprovided on its under side with a downwardly tapered portion 2 terminating in a circular aperture 3 surrounded by ashoulder 4 having a flanged outer edgeb. The upper portion of said casing is of rectangular outline and is similarly provided with a shoul der having a flanged outer edge which forms a seat to receive a slotted top plate 6 forming the burner portion of the construction. The casing is adapted to swivelly' engage upon the end of a' tapered mixing arm Thaving a flaredouter end 8. ,A source of gas supply 9 controlled by a needle valve 10 is positioned centrally ofthe flared outer end of said mixing arm andthe gas and air is thoroughly mixed as it passes through the mixing arm and casing to theslotted orifices of the top plate.

The mixing arm is turned upwardly at right angles at its inner end and isprovided with a shoulder ll andv flange12 adapted tointerfit with the complementary structure on the casing, heretofore described, to provide a gas-tight swiveled joint.

Upon the under side of said mixing arm adjacent said upturned end, an enlargement or boss 13 is provided, said enlargement having an aperture 14 to receive a bolt 15, the upper end of which extends throughthe top plate of the burner. A nut 16 on the end of said bolt is adapted to seat against the outer face of said boss 13 and serves to holdisaid top plate to the casing and to lock the casing in any desired position of angular adjustment about the mixing arm. .A second nut 17 may, if desired, be engaged upon the shank of the bolt to hold the companion plate members hereinafter to be .de

form product for the reason that the saws wear down and break in the course of time and slots of uniform width cannot be regu larly supplied. It has therefore been found desirable to form the top plate of two complementary castings 31,32.

Each of said castings comprise a longitu-' dinal central portion having lateral exten-.

sions. The upper ofsaid plate members is shown in Fig. 6 and includes a central section having a reinforcing rib 33 upon the upper side thereof having a series of short lateral ribs 3% reinforcing the lateral ex tension plates 35. Said extension plates arespaced from eachiother a distance of less than'thestandardwidth of the same and the extensions upon the opposite sides of said central portion are staggered with re spectto each. other. Bolt holes 38. are pro.-

vided at points spaced from the ends of said members along the central line thereof and adjacent said bolt holes suitable enlargements 39 project over the intervening spaces forreinforcing purposes. Said end extension plates 36, 37, are made of less width at one end and of greater width on the opposite. end in order to properly lit within the rectangularopening of the easings heretofore described. The lower of said plate members 32 is shown in Fig. 7' and -compr1ses an elongated central portion 41 suitably reinforced. by a rib on its under sideysaid rib having lateral extensions L2 reinforcing lateral extension plates 43 which are positioned in staggered relation on theopposite sides of said'central portion. Suit able bolt holes 44 are provided, as well -as enlargements 45 adjacent said bolt holesand projecting over theintervening spaces be-' tween adjacent extension plates. I

The lateral extension plates 43 of the bottom member are formed of somewhat less width than the spaces between the lateral extension plates of the top member so that when the topv and bottom members of the top plate are assembled laterally extend-- ing slots will be: provided between the adjacent lateral edges 46 of said respectiveplate members. The edges at the sides of said holes may be oppositely beveled so as to give to said holes a slight inclineflfrom the vertical asviewed from the side, as shown in Fig. 3. By making the lateral extension plates ofthe members of different widths the lateralslots on opposite sides .of the central portion of the top plate will tureexplosions when the fuel jets are ignit- 7 ed or extinguished.

As has beenv indicated, the companion members ofthe-top plate are held in fixed adjustment to each other by means of a nut upon one or bothof the securing bolts and the assembled top plate is then held to the casing by means of" other nuts or fastening elements secured to the lower ends of said: bolts. 1

In th form of construction illustrated in Figs. 8 and ,9, a burner of'circular outline, as viewed from above, is provided, said burner comprising a circular casing 51 equipped on its under side with meansfor attaching the same to a mixing arm similar to that described in connection with. the elongated form of construction. A two-part top plate 52'similar tothe top plate 6 heretofore described is also provided. The companion sections of said'top plate 53, 54, each carry fan-shaped radial extension plates 55, 56, preferably of equalsize which,when inter-fitted, provide .radial slots 57 between their adjacentlateral edges. Each of said plate members is provided with an enlarged central portion 61, 62, respectively, from which reinforcing ribs 63, 64, project radially centrally of each of said radialv extension plates! Said central enlargements are providedwith registering apertures 65, 66, through which a securing bolt 67. is'.passed.- Said bolt is of a length sufficient to .secure the circular casing to a mixing arm in the manner illustrated with the other form of construction shown in Fig. 2. A securing nut 68 may be used to hold the two complementary top plate members in adjusted position. V 7 In .each of the forms of constructions illustratedit will be noted the slots upon oppositesides of the central portion of the top plate areinterrupted by enlargements upon said plate structure. These enlargements will serve to .divert the fuel and air mixture-to the slotted orifices. The burner has been found to be extremely economical of fuel and is most efficient in operation. The parts are few in number and may be readily assembled or easily disassembled for purposes of adjustment and repair. 3

Qthcr forms may be employed embodying the features of my invention instead of. the one here explained, change being made in the form or construction, provided the elements stated by any of the following claims 01- 1-116 equivalent of such state d elements be employed, whetherproduced by jmy pre ferred method or by others embodying steps equivalent to those stated in the following claims.

I therefore particularly point out and distinctly claim as my invention 1. A gas burner comprising an elongated casing open at its upper side, a pair of interfitting members forming a top platelfor closing said casing, a rib extending longitudinally of each of said members, a series of lateral extensions on each side of said longitudinal ribs, means for securing said members to each other so as to provide laterally extending orifices on each side of said top plate in staggered relation to the orifices on the opposite side, and means for supplying a fuel mixture through said casing to said orifice r 2. A gas burner comprising an elongated bers to each other so as to provide laterally extending orifices onyeach side of said top plate in staggered relation to the orifices on the opposite side, reinforcing ribs extending from said central rib over each of said lateral extensions, and means for supplying a fuel mixture through said casing to said orifices.
